6. Process Accounting Setup on Linux

1. Compile and install process accounting software.

   The process accounting software package is available from http://sunsite.unc.edu/pub/Linux/system/admin/quota-acct-modified.tgz

2. Modify your system init script and turn on process accounting at boot time.

   Here's an example:

   # Turn process accounting on. if [ -x /sbin/accton ] then /sbin/accton /var/log/pacct echo "Process accounting turned on." fi

3. Create accounting record file "pacct."

   Your process accounting software will print out all commands executed to the file /var/log/pacct by default.

   To create the accounting record file:

   touch /var/log/pacct

   This record file should be owned by root, and it has read-write permission for root and read permission for anybody else:

   chown root /var/log/pacct chmod 0644 /var/log/pacct

4. Reboot.

   Now reboot your system for changes you made to take effect.
